 | // The purpose of this test is to verify that various invalid PCH files are | 
 | // reported as such. | 
 |  | 
 | // PR4568: The messages were much improved since the bug was filed on | 
 | // 2009-07-16, though in the case of the PCH being a directory, the error | 
 | // message still did not contain the name of the PCH. Also, r149918 which was | 
 | // submitted on 2012-02-06 introduced a segfault in the case where the PCH is | 
 | // an empty file and clang was built with assertions. | 
 | // CHECK-EMPTY: error: input is not a PCH file: '{{.*[/\\]}}badpch-empty.h.gch' | 
 | // CHECK-DIR:error: no suitable precompiled header file found in directory '{{.*[/\\]}}badpch-dir.h.gch |
